    Putting together the parts list: Centerpulls? Classic vs. Modern RDs for touring?

    I have a '70s Raleigh Record Ace I'm stripping down to a bare frame to rebuild from the ground up as a reliable rando ride along retro-grouch lines.

    I've got two questions to ponder - it currently has a set of Weinman centerpulls that are pretty long in the tooth. Should I replace them with another set of new quality centerpulls like the Paul Racer or Dia Compe GC610, or look into a set of modern side-pull calipers instead? I do plan on keeping the wheel size 27x1, so long reach calipers aren't needed.

    Also, since finding a Sachs Huret Jubilee or Rallye v1 in primo shape is about as likely as winning Powerball, what would be a good rear derailleur? I'm planning on a triple crank up front and a 13-32 5-cog freewheel out back, both by IRD, and nice Dia Compe Silver shifters. I'm looking for something beautiful as well as functional - Is it worth trying to restore the Suntour GT I've already got on there, or should I just go with a new Campy Comp Triple RD? Is there another new or NOS option I'm overlooking?

    A Campy Comp triple or an earlier Racing Triple (aka Racing T) works fantastically as a friction shifter, especially shifting a freewheel with a modern Shimano-like tooth design.

    A vintage solution is a Huret DuoPar. They won't index, but as friction they shift as well as a modern slant-design rear mech, due to the second vertical parallelogram (Duo Par). You need to be careful about how it will mount to the dropout, but they work very well.

    To me the big questions about any old mech are, freedom of motion, correct alignment (not bent), tight pivots and bearings, and need for lubrication. If it has integrity in all those dimensions and good roller wheels, it should function as if it were new.

    For a brief time, I ran the DuoPar with Suntour 7 Speed Barend Index shifters, and a Suntour Winner Pro 7 Speed freewheel, and it was a perfect combination.

    Side pulls like the Dia-Compe Gran Compe and Royal Gran Compe are pretty decent, and the Royal Gran Compes (in white or black) are beautiful looking.

    For a center-pull, "long in the tooth" means dirty, scratched, needs new rubber, and loose/sticky pivots. Old ones can be cleaned, polished, re-shoed, lubed, and have pivot bushings replaced. No real need to go for new brakes. That said, I might look for some dual-pivots. While I like CPs, I've always thought the more-elaborate cable arrangements are cluttery and less reliable.

    My UO-8 has some kind of wide DiaCompe on it, and they really work well.

    Just finished rebuilding an Italian bike I have, and I took a few pictures this morning on it's first post-rebuild run. Made sure I took a picture of the Royal Gran Compes ...

    +1 to Dual-Pivots, they stop really well and you can find ones that won't look horribly out of place. The main problem with switching to dual pivots is that they will mostly be for recessed nuts, and your frame is most likely not drilled for recessed brake nuts. If you want to go that route you can work around it though.

    If by Suntour GT you mean either Suntour Cyclone GT or V-GT, i'd say probably worth it to use it. They are very nice derailleurs. What's wrong with yours that it requires Restoring? I've broken a Cyclone or two, and they aren't awful to repair, but for the most part a cleaning with some degreaser and some lube should set it straight.

    I was gonna get an IRD 5 speed freewheel last summer but all the reviews I read said that many of them fail within the first couple hundred miles. Suntour Freewheels don't do that. I wanted a new one so i could have all those nice hyperglide style ramps and twisted teeth....so I went with a cheapo SunRace freewheel. Its got 1000ish miles on it now and has been perfect.
